摘　　要：介绍一种基于LabVIEW语言开发的针对道路水分运移研究的人工模拟降雨自动控制系统。该系统采用闭环控制算法,通过涡轮流量计、电动执行器和PPC(可编程计算机控制器)来控制各种雨型。试验结果显示:设计雨强和检测雨强的相对误差在5%以下;全套系统的重现性、稳定性和降雨空间分布的均匀性在97%以上;渐变降雨的线性率在85%以上。An auto-control system for artificial rainfall simulation based on LabVIEW to study water migration in road structures was introduced.The closed-loop control algorithm was adopted in the system,and the rain types were controlled by a turbo-flowmeter,electrical regulated valve and programmable computer controller.The test results indicate that the relative deviation between the design and practical rain intensities is below 5%.The fidelity and stability of the whole set of system as well as the uniformity of spatial distribution of the rainfall are all above 97%.The linearity rate of the shadowed rainfall is above 85%.
